earthrise - Detroit's Urban Farming Revolution | Forum

In the early 20th century the American city of Detroit was a booming
industrial powerhouse and world leader in car manufacturing. But since
the major car companies closed their factories, more than a million
taxpayers have moved out of Detroit, leaving behind more than 100 square
kilometres of vacant land, and nearly 40,000 abandoned houses. A group
of visionary residents are now sowing the seeds of an urban farming
revolution.
